It appears that the TH1520 I2C is already supported in the upstream kernel through the Synopsis Designware I2C adapter driver. This patch depends on the clock patch from Drew Fustini Link: https://lore.kernel.org/linux-riscv/20240426-th1520-clk-v2-v2-0-96b829e6fcee@tenstorrent.com and the pinctrl patch from Emil Renner Berthing Link: https://lore.kernel.org/linux-riscv/20240103132852.298964-1-emil.renner.berthing@canonical.com Changed from v1: 1. Remove redundant example for Synopsis DesignWare-I2C bindings 2. Remove Node Ordering commit as it has already been taken 3. Remove EEPROM label 4. Rebase on pinctrl and clock driver patches 5. Add pinctrl configuration 6. Replaced the fixed-clock with a correct configuration Signed-off-by: Thomas Bonnefille --- Thomas Bonnefille (3): dt-bindings: i2c: dw: Document compatible thead,th1520-i2c riscv: dts: thead: Add TH1520 I2C nodes riscv: dts: thead: Enable I2C on the BeagleV-Ahead .../bindings/i2c/snps,designware-i2c.yaml | 4 ++ arch/riscv/boot/dts/thead/th1520-beaglev-ahead.dts | 84 ++++++++++++++++++++++ arch/riscv/boot/dts/thead/th1520.dtsi | 50 +++++++++++++ 3 files changed, 138 insertions(+) --- base-commit: e1fb0b71c746f863fa49ff359d58c949538ce181 change-id: 20240425-i2c-th1520-fc3ce1a8b472 Best regards,
